BEST MODE FOR CARRYING OUT THE INVENTION

The following is the explanation of the details for the collectionmethod of a fragrance ingredient of the present invention.

Powder or chips of fragrant wood is processed by heating agitationextraction or by soaking extraction for extracting the essential oilingredient. After filtering, the extract is obtained by removing thesolvent. This extract is heated and the volatized fragrance in the headspace is led outside the system. The introduction of inert gas is moresuitable. The fragrance ingredient is collected in an absorption solventwhich becomes a fragrance collection liquid. By this method, a fragranceingredient that reproduces the original fragrance of fragrant wood isobtained. Also, the perfume composition containing this fragrancecollection liquid can reproduce the original fragrance of the fragrantwood. Also, the cosmetic containing this fragrance collection liquid canimprove the quality of aroma.

Extraction of Fragrance Ingredient

In the present invention, the powder or the pieces of the fragrant woodcan be used suitably as a fragrant wood material. The fragrant wood inthe present invention is a agarwood or a sandalwood etc. The agarwood isgrouped into 6 kinds which is called “Rikkoku”.

“Rikkoku” is derived from producing district of the fragrant wood, i.e.“Kyara”, “Rakoku”, “Manaban”, “Manaka”, “Sasora”, “Sumotara” etc. Manyof the fragrant woods are produced from the hinterland of Vietnam,Cambodia and Myanmar. However, the differentiation of a producingdistrict becomes meaningless now. The quality of tree is decided on thebasis of the figure and aroma of fragrant wood.

A solvent is used to extract the essential oil ingredient containing thefragrance ingredient in the fragrant wood in the present invention.Water, methanol, ethanol, isopropanol, diethylether, pentane, hexane,propyleneglycol, glycerin etc. or these mixture solvent etc. are usedfor the solvent that extracts the essential oil ingredient containingthe fragrance ingredient of the fragrant wood.
